Experts from the University of Rochester have found the reason we call feeling down “having the blues!” Because when we’re happy, colors seem brighter and morevivid… But when we’re depressed, the world looks gray and gloomy. That’s because our emotionsaffect the way our brainprocesses color! In other words, when we’re sad, our brain literally bleaches some of the color out of the images being sent from oureyesto ourbrain – and makes colors lessintense – and gloomier – across the board.
